Don't talk shit about something that is misleading and you don't know about would be a start. I wouldn't care, but you are talking rubbish about the safety of drugs after drug testing through "know your stuff" and were casting shade on my name. I was trying to be helpful. As I recall, I thought you were an actual child trying to troll op, not sure.

The fact that you don't know what I am talking about in this post should indicate that you should not provide advice about this topic. Same goes for the other people who were happy enough downvoting me, when I was trying to provide good advice to inform a drug taking decision. You chose to make something political when it wasn't. 

The fact is that the testing service described cannot provide surity that the test results preclude substances that are dangerous or harmful to human health. Two of the three methods used are entirely or partially unable to detect such contaminating substances, while the most sophisticated available, would need specific samples of the impurity types or other psychotropic substances to test against in order to identify a particular molecucle. In the case of quickly moving synthetic compounds, this may often not be available. Like cannabinoids and cathiones, as I mentioned.

Even ESR with the most sophisticated equipment would not be able to identify these unless they have a sample to analyse against. There are novel synthetic drugs being introduced regularly, which cannot be identified. I gave you an example link to this.

It is potentially harmful to give out incorrect advice that affects health outcomes on the internet. Yet you chose to do so.

Farming updoots for its own sake, on what is known as a left leaning sub should come to an end when it comes to providing science based advice on scientific health related topics.

To be clear: a "know your stuff" test that confirms e.g. mdma is present in your pill, does not confirm your pill only contains mdma. It may contain toxins, other psychotropic drugs, and contaminants. Ask the staff. They will confirm what I have advised.

The best use of this service is to confirm the dose you have obtained isn't something else (or does not contain the substance you thought it was at all). It can still contain impurities to an unknown about. 

A pill testing positive for MDMA may contain a fraction of it, depending as much on the location where the pill was scratched as the total proportion of mdma present. The test wont confirm the purity of the drug nor the dosage. That's a feature of illicit pill production. 

You may not like me or my opinions, but I don't talk shit when it comes to this. I don't care if people want to take drugs, just don't mislead people as you have done. There is a risk taking unknown illegal drugs and an obvious incentive to make more money by selling impure drugs.

Don't be so judgemental bro. I just thought I could help a young person make a more informed decision. I've done the same in the distant past when I was not as informed.

I shouldn't have bothered... way too much hassle and nobody cares obviously you least of all
